The mind refers to that part of an individual that consists of their cognitions, memories, sensations, emotions, motives, and perceptions. The mind is what enables individuals to think and reason. It consists of conscious and unconscious mental processes. Psychology attempts to explain and describe behavior and the cognitive processes behind behavior. Psychology is a science based on experimentation and systematic observation, enabling psychologists to form assumptions about behavior, the mind, and human functioning. These assumptions lead to the development of theories that attempt to explain aspects of human behavior or mental processes. As with all sciences, knowledge about general laws and patterns are obtained through experimentation and observation. The field of psychology consists of several different theoretical perspectives, and most psychologists closely adhere to the theoretical approach that most closely fits their perspective. However, many psychologists see value in different theories, and an eclectic approach to the study of psychology. These psychologists believe that no single theory perfectly explains human thoughts and behavior, but rather attempt to explain behavior and cognitive processes by drawing upon different theoretical perspectives. History of Psychology Early Greek Philosophers Throughout history, humankind has been interested in the nature of the mind and the factors affecting behavior. Many ancient Greek philosophers, such as Plato, Socrates, and Aristotle presented differing perspectives on human thought and behavior. Aristotle’s beliefs about logic, reasoning, and careful observation of the world formed the underpinnings of the scientific method. These philosophers believed the world, and by extension, human nature, could be divided into two parts: the body and the spirit. This concept is known as dualism. The debate over which aspect of a person is more powerful in determining behavior and cognitions is still relevant today as the field of psychology continues to expand. Chapter 1: History and Approaches 41 The Scientific Revolution During the scientific revolution, a great philosophical shift occurred. Whereas religion had asserted that the spirit of a person could not be studied using scientific means, a new generation of philosophers and scientists challenged these religious beliefs. Advances in astronomy, biology, and other areas demonstrated that human behavior could be scientifically studied. Rene Descartes (1596-1650) believed that the physical world behaved according to patterns and natural laws. However, Descartes did not believe the human mind and its processes could be observed or predicted, because the mind does not follow natural laws. He envisioned an interaction between the mind and body, with the mind controlling the body and the body constantly supplying sensory information to the mind. Descartes believed that some parts of the body, such as reflexes, are not under the control of the mind but are simply reactions to external stimuli. Descartes’s ideas were expanded upon by John Locke (1632-1704). Locke believed that even the mind is subject to natural laws. Locke’s perspective that truth and knowledge can be acquired through experiences and observations is referred to as empiricism. Locke is perhaps best known for his concept of “tabula rasa,” a term that refers to the belief that humans are born knowing nothing, or are essentially “blank slates.” According to this perspective, no knowledge is innate; everything a person knows must be learned from experience. Thomas Hobbes (1588-1679) rejected the idea of a soul and spirit. He believed that matter and energy are the only things that exist, a philosophy referred to as materialism. Everything experienced in a person’s conscious awareness is a result of processes of the brain. The field of behaviorism was greatly impacted by Hobbes’s philosophy. Theory of Natural Selection Discoveries in medicine and biology strongly influenced the field of psychology during the nineteenth century. Charles Darwin (1809-1882) proposed the idea of natural selection. This evolutionary theory asserted that all living things evolved over a period of millions of years. Natural selection assumes that variations among humans naturally exist, and the individuals most likely to survive and reproduce are those that are the strongest and fittest, or those that have adapted to their environment. Through the process of natural selection, the characteristics that ensure a species’ survival are the 42 CLEP Psychology ones selected. Evolutionary theory is one way that differences between species can be understood and explained. The Science of Psychology Begins Wilhelm Wundt (1832-1920) is considered to be the founder of the science of psychology in the year 1879. Wundt hoped to use the process of introspection, in which individuals observe and record their mental states, including thoughts and feelings, in response to various stimuli, in order to understand more about basic cognitive processes. From this experiment, Wundt and his mentee, Edward Titchener (1867-1927), developed the theory of structuralism, in which the mind can be broken down into its simplest components and then those components can be combined in order to make up the sum total of the individual’s experiences. Titchener is credited for bringing the science of psychology to the United States. William James (1842-1910), an American psychologist, disagreed with the idea of structuralism and offered the view that the function and uses of cognitive processes, or the mind, is more important than the structures of the mind, an approach known as functionalism. James is also the author of the first psychology textbook. One of James’s students, Mary Whiton Calkins (1863-1930), became the first female president of the American Psychological Association. Calkins is also credited with starting the first women’s psychology lab. She is noted for her studies of memory, which led to the development of the paired association technique. She was a highly influential professor of psychology and philosophy. Another female pioneer in the field of psychology is Margaret Floy Washburn (1871-1939). Washburn was the first woman to receive a Ph.D. in psychology. She is noted for her work in animal behavior development and for motor theory. G. Stanley Hall (1844-1924), who also studied under William James, is considered to be the founder of child psychology and educational psychology; he was also interested in evolutionary psychology. Hall was the first president of the American Psychological Association. Max Wertheimer (1880-1943) was one of the three founders of Gestalt psychology. He believed that thinking moves from the whole to the parts, and focused on the total experiences of an individual. Gestalt psychology takes a holistic approach to understanding the individual, and this approach rejects the idea that human thought and behavior can be separated. Chapter 1: History and Approaches 43 Dorothea Dix (1802-1887) was a social activist and reformer who advocated for mentally insane, indigent people. After visiting hospitals and noting the terrible ways the mentally ill were treated and abused, she successfully lobbied for the establishment and expansion of state hospitals for the mentally ill. Theoretical Approaches The theoretical perspectives above show an evolution of thinking in science that gradually moves away from using reason and logic alone, to become more and more scientific in nature. There are ten main schools of thought in contemporary psychology. It is absolutely essential that you understand each one, and know what distinguishes each approach. School of Psychology (starting year) Evolutionary 1850s Structuralism 1880s 44 Description Process of natural selection determines behaviors and thoughts that promote survival. The behaviors, traits and thought processes that are most beneficial to survival will be passed to the next generation. Used introspection to identify basic elements or “structures” of psychological experience. To understand “reading”, for example, research participants would describe their experience while reading. First laboratory dedicated to psychological research, University of Leipzig, Germany 1879. CLEP Psychology Important contributors Charles Darwin Wilhelm Wundt, Edward B. Titchener School of Psychology (starting year) Description Related to Darwinism, consciousness must have evolved because it was useful for something; it had a Functionalism function. To understand the origins 1890s and purpose of psychological phenomenon we should ask what it is used for. The unconscious mind determines thoughts and behaviors. The unconscious mind cannot easily be accessed, but influences our Psychodynamic behavior. The conscious mind 1890s includes cognitive processes that we can access and for which we are aware. Early childhood experiences shape personality and determine behavior Not possible to objectively study the mind, therefore study should focus on observable behavior. Classical conditioning was the basis Behaviorism for learning by association. Operant early 1900s conditioning refers to the effect of reinforcers (positive or negative) that strengthen or weaken the likelihood the behavior happens again. The study of mental processes, including perception, thinking, Cognitive memory, and judgments. Computer late 1800s, analogies guided research and 1960s, 1990s have now evolved to include neuroimaging of the brain. Important contributors William James, Father of American Psy. Sigmund Freud Carl Jung Alfred Adler Erik Erickson Ivan Pavlov John B. Watson, B. F. Skinner Hermann Ebbinghaus, Albert Ellis Jean Piaget Chapter 1: History and Approaches 45 School of Psychology (starting year) Description Social situations and culture influence thinking and behavior. Explains variations in behavior and Sociocultural thoughts as influenced by different 1950s social environments, roles, norms and values among people of different cultural groups. Study of the person, the selfconcept, self-esteem and an appreciation for the human condition. Takes a holistic approach Humanistic to understanding human behavior 1950s and improving the growth of the individual person. Maslow’s hierarchy of needs and Roger’s concept of unconditional positive regard are central concepts. Attempts to understand how biology, physiology, and genes Biological affect behavior. Cognitive processes, 1990s emotions, and behaviors are seen as direct results of biological factors. Human behavior is the result of an interaction between biological, Biopsychosocial psychological, and social factors. Each factor is equally important in determining thoughts and behavior. 46 CLEP Psychology Important contributors Fritz Heider Leon Festinger Stanley Milgram Abraham Maslow, Carl Rogers No single researcher recognized George Engel Modern Subfields in Psychology The AP Psychology exam requires you to be familiar with the subfields of psychology. Different schools of psychological thought have led to different subfields and professions in the 21st century. The following is a list of the subfields and their definitions. Many universities offer masters or doctoral degrees in these subfields. Modern Subfields of Psychology Biological psychology Clinical psychology Examines the mind-body connection. Understand how biology, physiology, and genes affect behavior. Diagnose, assess, treat, and prevent emotional, behavioral, and psychological disorders Counseling psychology Help individuals achieve and maintain healthy functioning. Includes social, vocational, educational, developmental, and healthy habits Developmental psychology Studies how and why children/adults change over the lifespan. Can include various theoretical approaches. Cognitive psychology Educational psychology Examines mental processes involved in social settings, information processing and decision-making. Studies learning, motivation, instruction, and assessment in educational settings. Examines and improves the interaction between teaching and learning. Chapter 1: History and Approaches 47 Experimental psychology Studies humans and animals to understand sensation, perception, memory, learning and motivation. Human factors psychology Design products, equipment and technology for human interaction. Often focused on performance and safety. I/O psychology How people act in organizations and the workplace. Goal is to increase performance, motivation, and job satisfaction. Personality psychology Studies individual differences in emotions, cognitions, and behavior. How cultural factors influence personality development and expression. Psychometric psychology Examines the design, administration and interpretation of tests. Measures variables such as aptitude, personality, abilities, and interests. Experimental Social psychology Examines the way people relate to others using experimental methods. How attitudes are formed, changed, and affect the behavior of others. 48 CLEP Psychology Practice Questions 1. Which approach deals with issues of self-concept and free choice? (Lower order) (A) sociocultural approach (B) biological approach (C) humanistic approach (D) functionalism (E) Gestalt psychology The correct answer is C. Humanistic psychology focuses on the study of free will, self-concept, awareness of the human condition and aspects of consciousness. The sociocultural approach studies how social and cultural factors influence thoughts and behavior. The biological approach views behavior as being a result of biological and genetic factors. Functionalism is a theory that states that the functions of the mind are more important than the actual components of the mind. Gestalt psychology seeks to understand the individual in view of the person’s total experiences. Although very similar to humanistic psychology, gestalt psychology does not focus on self-concept. 2. Which early theoretical perspective had the greatest influence on the field of behavioral psychology? (Higher order) (A) empiricism (B) dualism (C) natural selection (D) materialism (E) tabula rasa Chapter 1: History and Approaches 49
